The present study provides information about children with autism spectrum disorder (ASD) who are involved in the child protection system in a large, Midwestern state. Findings revealed that children with ASD (and children with other disabilities) were more likely to receive services from the child protection system (CPS) than children without disabilities. Children with ASD in CPS were more likely to be elementary school-age (6–10 years) and Caucasian than other children involved in CPS. Children diagnosed with ASD and other disabilities were significantly overrepresented for physical abuse as the primary reason for involvement in CPS. Parental mental health issues were more evident than was expected for families of children with ASD (17%) as compared with children diagnosed with other disabilities (10%) and children not diagnosed with any disability (10%). The implications of these findings as they relate to interventions for children with ASD in CPS are discussed.

The impact of supplemental UV-B (sUV-B) radiation and heavy metals: Cd (68 µmol.kg -1 soil) and Ni (68 μmol.kg -1 soil) singly and in combination was studied on photosynthetic and non-photosynthetic pigments, metabolites, enzyme activities, biomass accumulation and the net primary productivity of spinach (Spinacia oleracea L. var. All Green), a common leafy vegetable plant. Both the stresses individually and in combination resulted in the reduction of photosynthetic pigments, ascorbic acid, and catalase activity, whereas a reverse trend was observed for anthocyanin, flavonoids and proline content, lipid peroxidation and peroxidase activity. The interactive effects of both the stresses were, however, less than additive. Combined treatment of sUV-B + Cd was more deleterious as compared to sUV-B + Ni and other individual treatments. Key words: Spinaicia oleracea, biomass, cadmium, enzymes, nickel, pigments, ultraviolet-B.Efeitos interativos entre radiação ultravioleta B suplementar e metais pesados no crescimento e características bioquí-micas de Spinacia oleracea L.: Estudou-se o impacto de radiação UV-B suplementar (sUV-B) e dos metais pesados Cd (68 µmol.kg -1 solo) e Ni (68 μmol.kg -1 solo), isoladamente ou em combinação, sobre pigmentos fotossintéticos e não fotossintéti-cos, metabólitos, atividades enzimáticas, acúmulo de biomassa e produtividade primária de espinafre (Spinacia oleracea L. var. All Green). Ambos estresses, individualmente ou em combinação, resultaram na redução dos pigmentos fotossintéticos, áci-do ascórbico, e atividade de catalase, sendo que uma tendência oposta foi observada para o conteúdo de antocianina, flavonói-des e prolina, peroxidação lipídica e atividade de peroxidase. Os efeitos interativos de ambos estresses foram, no entanto, menos que se fossem aditivos. O tratamento combinado de sUV-B + Cd foi o mais deletério quando comparado com sUV-B + Ni e outros tratamentos individuais.
